The german covers really are fantastic. I would love to see a resource of them, or some higher quality posts. [Most of the ones that turn up on google are pretty low quality.]
Don't know if you can call them "higher quality", but I've written an article for the G&T Show website collecting all covers that Cross Cult changed: http://www.gandtshow.com/?p=3016
ETA: If you see the article before it gets fixed: I'm already aware that the Crucible covers aren't German creation, must have had a total brain-fart when I included them.
